PPSh-41 on the left. It really just folds open and there’s the bolt on a spring.

Those are some very American pineapple grenades amid the variety of potato-mashers.

I admit no ability to identify the two revolvers that Sergei Ramboski has tucked into his bandolier.

Might they be F1 grenades?

I don’t have a good eye for firearms in general, but I would guess a Nagant M1895 just by like, probability/availability. Also I think that’s a loading gate on the side of it, which would be unusual in other revolvers of this period.

Good spot on the F1s. Like a Mk 2 with a stovepipe hat. We lost some aura once grenades became plastic bottles full of semtex and concertina wire.
